To all 'whom it may concern:

Be it known that I, IsAAcBERTIm a citizen of the United States, and residing at New York, in the county ofv New York and 1() pertains to make 'and use, the same..

This invention relates to starting mechanisms for power shafts, such as gas engine crank shafts, steam engine shafts andthe like, and theJ object of the invention is to provide a' device of this-,fclassl which is simple in construction and operation and elicient in use andv is specially designed'y for use in connection with automobile en-;

. gines, whereby the same may be cranked from the drivers seat of the vehicle.

lThe invention is fully .disclosed in the following specification, of whichthe accompanying drawing forms 'a part,in which vthe separate parts" of my improvement 'are 25 designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional plan view of my' improved starting Imechanism and -indicating its connection with the frame work of the Vehicle;

. Fig. 2 a partial `section on the line 2-.2 of Figlgand, l.

Fig. 3 a View similar to Fig. but showing the parts in a different position. In the drawing I have indicated at a th front side members of the chassis frame'of an automobile, and at b I have shown the /end of a crank shaft in which thestarting pin b2 is mounted.

In the practice of my' invention, I employ a frame c which may be secured to the chassis frame of the vehicle, as 'clearly indicated at c2, or may be secured to any other,V

part of the framework of the vehicle, and

I said frame is provided with forwardly di- -rected arms c3 in which is mounted ra transverse shaft d, centrally of which is secured a segmentalspiral gear e which meshes with a spiral gear e2 mounted on a shaft fhaving 5() a bearing in the frame c at. c?. The vother end of the shaft f. is provided with'la starting crank ratchet or clutch head ghavin a plurality of teeth-like projections g2 whlch are adapted to operate in connection with the starting/.pin b2 on the end of the shaft b.

lever la, to the end of which pivoted a\ link rod i which is pivoted to a hand-operated lever j'as shown at 722,. and the lever j is pivoted to a shaft j2 mounted in the frame Work of the vehicle inl any desired manner.

Ihe positionof the parts shown in F igs." 1` and 2 is the normal position thereof, or the position saidv parts assume when the vehicle is at a` stand still, or when in operation, and when it is desired yto crank the engine the hand lever j is moved from the"v I positionfindicated in dotted 'lines at :v in

Fig. 3- to the full line position indicated in said figure, and this movement is continued until said lever is indicated at :122' in Fi l 3, which operation first rota s the .sha d which in turn rotates the spiral gear segment e, and moves the spiral gear. e2 and the l clutch' head y thereon into the position shaft f is the spiral gear segment e which operates the spiral gear e2 to accomplish-this result, andthe shaft' b which is integralwith, or in operaengine 1s correspondingly rotated.'

It will be understood that the lever 7'- is' movedbackwardly by hand into its normal vp'osition'and the above operation may be tive connection with the crank shaft of the ment the driver of the vehicle may start the j engine, while sitting in the drive seat and accomplish this result with a minimum f amount of exertion by reason of the construction of my improved lstarter, and it will be understood that my invention is not limited to the rspecific means, herein shown and described, for supporting my improved mechanism, nor'to the location thereof, and changes in and modifications of the details of construction 'as shown may be made, Within the scope ofthe appended claims, without departing from the spirit of my in vention, orsacrificing its advantages. Having fully described my invention, what I claim as new and desire tov secure by Letters ]atent,is:f-l l 1. A starting mechanism of the class described, comprising a shaft, a spiral gear segment mountedl on said shaft, another shaft mounted at right angles to said firstnamed shaft, a yspiral gear on said last named .shaft and operated by said vgear segment and a .clutch .hea-fi connected with said `shaft Land vm operative connection tatinV said shaft by means of said gear and vspira Vgear segment. Y

3. lIn a dev-ice vof the class described, a frame, .a main shaft mounted in said frame, al supplemental shaft movably mounted 4'n said frame at right angles to the main shaft, a spiral ygear secured to one end of the supplemental shaft, a spiral gear segment secured. to the main shaft a..d in operative connection with said gear, a clutch member mounted-on the other end of the supplemen'f tal shaft, a hand-operated lever mounted adjacent to the drivers seat of a vehicle, rod pivoted tto said lever, and a lever secured to the .main shaft and with `Which said flink rod is pivotally connected Wherelby the operation of said hand-operated lever will 4rotate the main shaft to movethe clutch head on the end of the supplemental shaft into operation with the crank shaft Yof an engine and rotate said shaft by means ,of the gear and spiral gear segment on said shaft.

y .4. In a device of the .class described, a

a link frame, a main shaft mounted in said frame, a supplemental shaft movably mounted 1n said frame at right angles to the mam shaft,

a spiral gear secured to one end of the suption of the chassis frame of a vehicle, of a frame having forwardly directed bearing members, main lshaft mounted in said bearing members, a supplemental shaft movably mounted lin said frame centrally thereof and in a plane at right angles to the main shaft, a spiral gear secured to one end of the supplemental shaft, a clutch member secured to the'other end of said shaft, a spiral gear secured to the main shaft and in operative connection with the spiral gear on the supplemental shaft, an operating lever mounted in the frame of the vehicle adjacent to the drivers'seat, and means for placing said lever in operative connection With said main shaft.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 25th day of January, 1918.
